For more than a century, a patch of cold water south of Greenland has resisted the Atlantic Ocean’s overall warming, fueling debate amongst scientists. A new study identifies the cause as the long-term weakening of a major ocean circulation system. Researchers from the University of California, Riverside show that only one explanation fits both observed...

The Arctic is warming at three to four times the global average. However, new research suggests the slowing of a key ocean current could reduce projected Arctic warming by up to 2 degrees Celsius by the end of the century. For years, scientists have warned that unchecked Arctic warming could lead to devastating consequences, threatening...

A study led by a UC Riverside atmospheric scientist predicts that unchecked carbon emissions will force tropical rains to shift northward in the coming decades, which would profoundly impact agriculture and economies near the Earth's equator. The northward rain shift would be caused by complex changes in the atmosphere spurred by carbon emissions that influence...

Anthropogenic aerosols — aerosols originating from human activity — and greenhouse gases, or GHGs, have helped modulate the storage and distribution of heat in oceans since the industrial age. Isolating and quantifying the effects of both forcers using coupled climate model simulations, a University of California, Riverside-led team has found that anthropogenic aerosols and GHGs...

"New research has identified a lesser-known form of ozone playing a big role in heating the Southern Ocean — one of Earth’s main cooling systems. Ozone is a gas composed of three oxygen atoms. Many studies have described ozone in the stratosphere, and its role in shielding people from the sun’s harmful ultraviolet radiation. Closer...

Humans must reduce carbon dioxide and aerosol pollution simultaneously to avoid weakening the ocean’s ability to keep the planet cool, new research shows. Aerosol pollution refers to particles in the air emitted by vehicles and factories that burn fossil fuels. This pollution contributes to asthma, bronchitis, and long-term irritation of the respiratory tract, which can...
